T0 aZZ whom it may concern:

. Be it known that I, PATRICK WILLIAM CLARK, a citizen of the United States, residing at Superior, in the county of Nuckolls and State of Nebraska, have invented a new and useful Car-Brake, of which the following is a specification.

This invention relates to car-brakes, and more particularly to means whereby the brakes may be applied by the utilization of pofver produced by the rotation of the carax e.

A still further object is to provide means whereby the brake-applying mechanism may be thrown into operative position by means located within convenient reach of an operator standing adjacent the car.

The invention consists of hangers whichare secured upon the car and which constitute bearings for a shaft slidably mounted therein and on which is located a gear and a drum. The ordinary brake-chain is connected at one end to the drum, and mechanism is located, preferably, at one side of the car, whereby the shaft can'be moved so as to bring the gear supported thereby into mesh with a gear upon one of the axles of the car. Resilient means, such as a coiled spring, is interposed between the chain and the brakebeam, so as to ease the strain upon the mechanism while the brakes are being applied.

The invention also consists ofcertain other novel features of construction and combination of parts, which 'will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings, Figure 1 is a side elevation of the mechanism and showing the adjoining portion of the car, and Fig. 2 is a bot tom plan view of said mechanism.

Referring to the figures by numerals of ref erence, 1 is a car-axle on which'is secured a gear 2. Hangers 4 are secured to the car adjacent the sides thereof, and formed within these hangers are slots 3, in which is rotatably mounted a shaft 5. A gear 6 is mounted upon and rotates with the shaft and is so disposed as to move into mesh with the gear 2 when the shaft is shifted within the slots 3 and toward the axle.

A small drum 7 is disposed upon the shaft 5, and one end of a chain 8' is fastened thereto. This chain is secured to the usual brake-beam,

J 2 will of course rotate with axle- 1.

Collars 10 are loosely mounted on the shaft 5 and are connected by means of a yoke 11, secured by a stem 12 to one end of a lever 13, which is fulcrumed beneath the car and is adapted to be operated by an actuating-lever 14, which is preferably disposed upon the side of the car at a point where it canbe conveniently reached from the ground by the operator. It is thought that the operation of the brake will be clearly understood from the foregoing description. I

When the car is moving forward, the ear Shou d it (notshowm) and astron-g coiled spring be desired to apply the brakes, the operator grasps the actuating-lever 14 and swings it upon its fulcrum so as to cause the lever 13 to 1 press backward u on rod 11 and collar 10. The shaft 5 will therefore be slid within the slots3 and toward the axle, and the gear 6 will be brought into mesh with the gear 2. Said gear 6 will therefore be caused to rotate and chain 8 will be wound upon the drum and op erate the brake-beam and cause the brakes to be applied. In order that no injury will resuit to the mechanism after the application of the brakes and during any further forward movement of the car, the sprin 9 is utilized so as to bring the parts to a gra ual stop.

Mechanism such as herein described is particularly adapted for use upon freight-cars ing shifted. The mechanism may, however, be used equally as well upon cars of other varieties.

Instead ofusing intermeshing gears I can employ friction-disks, and it is to be understood that by the term gears I intend to designate either intermeshing or friction devices of this character.

What is claimed is- 1. The combination with arotatable axle, and a power-transmitting device'rotatable therewith; of hangers having curved slots therein, a shaft rotatably mounted within said slots and adapted to slide therein, a power-transmitting device rotatable with the shaft, a brake-chain secured to and adapted to be held upon the shaft, and means for moving both ends of the shaft in unison to shift because of the convenience with which the brakes can be applied while-the cars are beated lever, and connections between the le'- ver and yoke for shifting the power-trans mitting devices into operative relation.

In testimony that 1 claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

PATRICK WILLIAM CLARK.
